Gait Technology

BMVSS has set up a state-of-the-art gait research center at the BMVSS campus in Jaipur named after German philanthropist and publisher Paul Hamlyn that is supported by the U.K. Foundation and the Indian Railway Catering and Tourism Corporation.

These developments promise further improvements to the performance and life span of the Jaipur foot by addressing the issue of natural gait cycle emulation by lower limb prosthesis.

The Model Predictive Controller (MPC) for gait control of the Jaipur Foot; developed by Bhagwan Mahaveer Viklang Sahayata Samiti, anticipates the future gait cycle for the prosthetic leg based on initial time horizon of the human gait cycle through online error minimization. The simulation results of the MPC actuated through the human gait cycle (adopted from literature) are in line with that of the natural gait cycle for hip, knee and ankle joints. The developed controller is implemented to control the knee joint of a customized version of the Jaipur Foot. The actuation was through able-bodied knee joint gait profile during walking on a treadmill at normal speed. The initial results of the Jaipur Foot knee joint follows the human knee gait profile.
